We strongly recommend that the IP Lockouts feature be used instead of Access Control because IP Lockouts work at the server-level, blocking access when an offending IP address tries to establish a connection. As a result, the IP Lockouts feature is more efficient and secure, as it identifies an attack when the attack begins and it puts host resources out of reach.
When an IP address is added to Access Control and IP Lockouts is enabled, the IP address does not get added to the Blacklist. The Access Control setting will be used, so the IP address will be able to connect to the server, but then will be blocked at the host-level.
This page allows you to control access to this host by IP address.
